Merge lp:~brunogirin/charms/precise/python-django/username-password into lp:~charmers/charms/precise/python-django/trunk

[Bruno Girin]

Added support for user name and password in the VCS repo to support repositories like the github private repositories. This implementation only works with URLs of the form protocol://domain/file and stores user name and password in the ~/.netrc file with 600 permissions.

[Brandon Holtsclaw (imbrandon)]

Looks good to me, merging.
